I recently acquired a Relm RH256NB serial number 681-A23702. The unit powers up but I have not been able to program it. I did get a reply from Relm for an inquiry for a user manual and they were going to mail it to me. Well that was a month ago and I have yet to get anything.

Does anyone have a copy of the use manual for this radio? I also need to know how to program it. All the information I have found does not match this radio. It does not have the switch on the board that all the programming I have been able to find refers too.

Ok, I have figured out how to get this radio programmed but have a microphone issue. I still have not heard anything from Relm about the owners manual. Does anyone have a copy of one and with any luck a schematic?
